Answer:
x = 6Step-by-step explanation:
If you square both sides you get:
5x - 7 = 3x + 5Solve it for x:
5x - 3x = 5 + 72x = 12x = 6Answer:
x = 6
Step-by-step explanation:
[tex]\sqrt{5x - 7}[/tex] = [tex]\sqrt{3x +5}[/tex] ( square both sides to clear the radicals )
5x - 7 = 3x + 5 ( subtract 3x from both sides )
2x - 7 = 5 ( add 7 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Find the y-intercept and the slope of the line.
y=2/3
Answer:
y-intercept = 2/3
Slope = 0
Step-by-step explanation:
Equation of Line is y=mx+c
where m is the Slope
and c is the y-intercept
so for our Problem
y=2/3
which can be rewritten as y=0x+2/3 (y=mx+c)
so Slope =m=0
and y-intercept = c = 2/3
George bought tickets for the school fair. The tickets cost $4 each plus a $5 handling fee. The total cost was $21.
Let x represent the number of tickets George bought. Write an equation that represents George’s purchase.
4x+5=21
4$ each ticket that means 4x plus 5$ the handling fee
= the total cost 21 $
What is the ratio 2 1/7 to 3 4/7 as a simplified fraction?
Show how to solve \/2x+1-4=-1
Answer: X=5/8
Step-by-step explanation:
2*x-1/4-(1)>0
Step 1 Simplify: 1/4
(2x-1/4)-1>0
Step 2 Rewrite the whole number in an equivalent fraction:
(Subtract a fraction from a whole)
2x=2x/1=2x*4/4
Adding Fractions that have a common denominator:
2x*4-(1)/4=8x*1/4
The equation at the end of step 2:
(8x-1)/4-1>0
Step 3 Rewrite the whole as an equivalent fraction:
1=1/1=1*4/4
Adding Fractions that have a common denominator:
(8x-1)-(4)/4=8x-5/4
The equation at the End of Step 3:
8x-5/4>0
Step 4:
Multiply both sides by 4 then Divide both sides by 8.
So the answer is
x>5/8

A cellular phone tower services a 20-mile radius. A rest stop on the highway is 5 miles east and 12 miles north of the tower. If you continue driving due east, for how many more miles will you be in range of the tower?
Answer: 11
I just need a explanation, thank you!
The tower will work within next 11 miles inasmuch the drives moves through the road.
How to determine a distance inside a cellular phone towerThe maximum distance corresponds to the radius of the tower ([tex]r[/tex]), in kilometers, the east direction corresponds to the +x semiaxis and the north direction corresponds to the +y semiaxis. The angle and magnitude of the rest stop are found below:
[tex]l = \sqrt{5^{2}+12^{2}}[/tex]
[tex]l = 13[/tex]
[tex]\theta = \tan^{-1}\left(\frac{12}{5} \right)[/tex]
[tex]\theta \approx 67.380^{\circ}[/tex]
To determine distance within the cellular phone tower works we need to solve the following system of linear equations representing vector components:
[tex]5 + x = 20\cdot \cos \theta[/tex] (1)
[tex]12 = 20\cdot \sin \theta[/tex] (2)
By (2):
[tex]\theta = 36.869^{\circ}[/tex]
By (1):
[tex]x = 11[/tex]
The tower will work within next 11 miles inasmuch the drives moves through the road. [tex]\blacksquare[/tex]

Answer:
4c - 8
Step-by-step explanation:

4c - 8
you have to multiply the 4 by each one in the bracket
but c is a variable so you dont know what number it is. so you just write 4c because that means 4 times whatever c is
Find the value of x for the triangle.
Answer:
Step-by-step explanation:
8x + 2 + 70 + 60 = 180 {angle sum property of triangle}
8x + 132 = 180
8x = 180 -132
8x = 48
x = 48/8
x = 6
Here, we are given a triangle with 2 of its angle , the third angle is in the form of variable equation .
We will use the angle sum property of triangle to find the value of variable i.e x in the given triangle.
Here,
➙ ∠A = 70°
➙ ∠B = 60°
➙ ∠C = 8x + 2
Angle sum propertyIt states that the sum of all angles of a triangle is 180°
ㅤㅤㅤ➙ ∠A + ∠B + ∠C = 180°
ㅤㅤㅤ➙ 70° + 60° + ∠C = 180°
ㅤㅤㅤ➙ 130° + ∠C = 180°
ㅤㅤㅤ➙ ∠C = 180° - 130°
ㅤㅤㅤ➙ ∠C = 50°
ㅤㅤㅤ➙ 8x + 2 = 50
ㅤㅤㅤ➙ 8x = 50 - 2
ㅤㅤㅤ➙ 8x = 48
ㅤㅤㅤ➙ x = 48 / 8
ㅤㅤㅤ➙ x = 6

A room is 12 feet long, 14 feet wide, and 11 feet high. The walls, ceiling, and floor are all to be painted the same color. How many square feet must be covered with paint?
Answer:
908 feet²
Step-by-step explanation:
To paint walls, we will be looking for surface area.
Since this is a room and we have three measurements, we can assume there will be the floor, the ceiling, and four walls. This means we will be looking for 6 sides in total.
-> See attached for a diagram I made of the sides we need
-> Keep in mind opposite pairs of walls will be the same, and the floor and ceiling will be the same.
We end up with the following sides:
11 * 12
11 * 12
11 * 14
11 * 14
12 * 14
12 * 14
We can simplify this to the following:
(2(11 * 12)) + (2(11 * 14) + (2(12 * 14) = 908 feet²
908 feet² must be covered with paint.

x - y = 12
The x-intercept is when the value of the y-coordinate is 0.
[tex]x - 0 = 12\\ x = 12[/tex]
Thus the x-intercept is at (12,0).
The y-intercept is when the value of the x-coordinate is 0
[tex]0-y=12\\y = -12[/tex]
Thus the y-intercept is at (0,-12)

x≥−12
x is greater than or equal to negative 12
x≥12
x is greater than or equal to 12
x≤12
x is less than or equal to 12
x≤−12
x is less than or equal to negative 12
Answer:
[tex]x\geq 12[/tex]
x is greater than or equal to 12
Step-by-step explanation:
We first start off with recognizing that this is an inequality, and that the answer choices involve solving for [tex]x[/tex].
I suggest that you write out the steps one-by-one and don't skip any so that making a mistake is less likely.
Rewrite the original equation:
[tex]-\frac{3}{4}x + 2 \leq -7[/tex]
Use reverse PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) order to isolate [tex]x[/tex]:
Subtract 2 from both sides: [tex]-\frac{3}{4} x \leq -9[/tex]
Divide both sides by [tex]-\frac{3}{4}[/tex] (this flips the inequality symbol since we're dividing by a negative number): [tex]x\geq 12[/tex]
Your final answer is:
[tex]x \geq 12[/tex]
x is greater than or equal to 12

The tree diagram represents an
experiment consisting of two trials.
The probability defined as P(A and C) is the probability of P(A) × P(B) = (0.6 × 0.3) = 0.18
The probability of A ; P(A) from the tree diagram is 0.6
The probability of B ; P(B) from the tree diagram is 0.3
The probability, P(A and B) equals ;
P(A) × P(B) = 0.6 × 0.3 = 0.18
Therefore, probability of A and B is 0.18
